You are driving on a circular ramp of radius 72.0 m on an icy January day. The ice-covered ramp is banked at a 23.0° angle, and you anticipate that the ramp is not going to provide any significant friction to help keep your car on the road. (a) What must your speed be so that your car does not slide off the road? (b) What are the direction and magnitude of the net force acting on you at that point? Your mass is 72.0 kg

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
